Book excerpt: This book draws upon contemporary Irish and international research which explores the critical interplay between education studies and sexualities. Scholars from Ireland, Canada, Spain, the U.K. and Sweden employ the conceptual lens of Queer Theory to interrogate and destabilise long-standing regimes of truth/knowledge, and in so doing, highlight the suitability and applicability of this theoretical perspective within educational discourses. By reframing and repositioning gender identity/expression as a performative expression on a fluid continuum, this book provokes readers to (re)view how they see education, pedagogy and schooling. The book interrogates what happens to teaching, and teachers, when queerness permeates their practice, thus exposing the ways in which heteronormativity informs and shapes our places/sites of education. This book was originally published as a special issue of the Irish Educational Studies journal.
